  • the moveable member 52 of the flapper valve 50 is moved to an open position (by an operator) before loading the canister assembly 32 into the liner 34 of the collector module 14 of the vacuum assembly 10. Because the moveable member 52 is biased in a closed position over the air intake port 44 of the canister assembly 32, the operator needs to move moveable member 52 from the closed position, depicted in FIG. 4 , for example to the open position. To move the moveable member 52 into the open position, the moveable member 52 is rotated in a direction away from the intake port 44, such as a downward direction, by way of hinges 64 that couple the flapper valve 50 to the canister assembly 32.
  • the moveable member 52 is rotated until the projection 56 is snapped over and locked by the locking member 62 of the canister 35. So configured, when in the fully open position, the projection 56 and locking member 62 together create a latch mechanism 66 to secure the moveable member 52 in the fully open position. In this manner, the flapper valve 50 is moved from a closed position to a locked and fully open position, and the latch mechanism 66 secures the flapper valve 50 in the fully open position.
  • the canister assembly 32 of the collector module 14 is depicted being lowered into the liner 34. More specifically, as the canister assembly 32 is initially lowered into the liner 34, the flapper valve 50 is disposed in a fully open position. Upon further movement into the liner 34, the tab 59 of the moveable member 52 contacts an angled portion 68 disposed on an inside surface 70 of the liner 34. As a result, the projection 56 disposed on the outside surface 54 of the flapper valve breaks away or becomes detached from the locking member 62 of the canister 35.
  • this contact forces the latch mechanism 66, which includes the projection 56 of the moveable member 52 snapped over the locking member 62, to become unlatched, allowing the moveable member 52 to be detached from the locking member 62 in the open position, for example.
  • the canister assembly 32 is depicted completely disposed within the liner 34.
  • the projection 56 becomes detached from the locking member 62 of the canister 35 (see, e.g., FIG. 7 )
  • the flapper valve 50 is biased in a closed position
  • the moveable member 52 of the flapper valve 50 automatically swings or moves in an upward direction to contact an edge 72 of the liner 34.
  • the moveable member 52 of the flapper valve 50 is in an open position and a hose (not depicted) is able to be attached to the air intake port 44 of the canister assembly 32, allowing the vacuum cleaner assembly 10 to be in used, for example.
  • the flapper valve 50 stays attached to the canister 35, and the moveable member 52 of the flapper valve 50 initially continues to ride along the edge 72 of the liner 34. Once the moveable member 52 of the flapper valve 50 clears the liner edge 72, the moveable member 52 rotates back into the closed position (see, e.g., FIG. 4 ), covering the air intake port 44. So configured, this helps to retain any debris disposed in the canister 35 and prevents debris from falling out during removal of the canister assembly 32.
  • an interior area of the liner 34 includes an angled wall section 73 having the air intake opening 38 disposed in a center portion of the angled wall section 73 and the edge 72 partially surrounding the air intake opening 38.
  • An extending member 75 extends from one side of the angled wall section 73 and includes a surface 77 having a rib 79. The rib 79 is disposed perpendicular to the surface 77.
  • one or more of the extending member 75, the surface 77 of the extending member 75, and/or the rib 79 guide the tab 59 of the moveable member 52 away from the liner 34 to help control the closing of the moveable member 52.
  • surfaces of one or more of the extending member 75, the rib 79, and the tab 59 cams the moveable member 52 away from the liner 34 during removal of the canister 35, helping to control the closing action of the moveable member 52 when the canister 35 is being removed from the liner 34.
  • the interaction of these surfaces also guide the moveable member 52 away from a seal (not depicted), such as an o-ring, used when the hose is snapped into the air intake opening 38 of the liner 34, preventing interference with the seal mounting.

  • the foam section 80 and the grill insert 82 remain in place during operation of the vacuum cleaner assembly assembly 10 and when the canister assembly 32 is removed from the liner 34, which helps prevent debris or other materials from entering the airflow path.
  • debris is retained within the canister 35 because the flapper valve 50 remains attached to the canister 35 and automatically moves to the closed position. So configured, this further prevents debris from falling out of the canister 35, creating a more seamless and cleaner removal of the canister assembly 32 from the liner 34 of the collector module 14 when the canister 35 is emptied, for example.
  • the operator of the vacuum cleaner assembly 10 of the present disclosure needs to lock the flapper valve 50 into a fully open position, as explained above, other required operator actions are reduced.
  • the canister assembly 32 is ready to be disposed within the liner 34 of the collector module 14.
  • the flapper valve 50 contacts a portion of the liner 34, causing the flapper valve 50 to automatically move from the secured and/or locked position to an unlocked position.

  • the moveable member 52 of the flapper valve 50 automatically moves to the closed position over the intake port 44 of the canister assembly 32, as the flapper valve 50 is biased in the closed position over the intake port 44.
  • the vacuum cleaner assembly 10 requires less time to operate and is more efficient than conventional vacuum cleaner assemblies.
  • any reference to "one example” or “an example” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment.
